一种情景驱动的探索式服务组合方法
|
摘要
虚拟计算环境中的大规模协同工作经常存在需求不确定和动态多变的情况,需要以边执行、边探索的方式求解问题.针对这类需求,结合非常规突发事件应急处置过程中根据情景信息迅速构建应用的实际问题,提出了一种情景驱动的探索式服务组合方法.重点探讨了以Web服务发布的分布、自治的资源的汇聚机制和服务即时推荐机制.通过非常规突发事件处置的案例表明,该方法能够在大规模协同工作中,辅助用户快速准确地构建业务流程,应对需求不确定和动态多变的情况.
Uncertain and dynamic requirements always exist in large-scale collaborative work in virtual computing environment,which needs problem-solving methods in a try-and-error manner.Related to such requirements and real problems in unconventional emergency handling,a novel context-driven approach to exploratory service composition is proposed.Focuses are on convergence of distributed,autonomous resources wrapped in Web services and on-the-fly recommendation of services according to context.A case study in unconventional emergency handling illustrates that the approach can help users deal with uncertain and dynamic situations,and construct business process exactly and rapidly in large-scale collaborative work.
